Card Slot Routing Notes
Routing to and from I/O cards is handled by signal paths. The TT24 supports a maximum of
32 input and output signal paths to/from each card slot. But, some cards (LP48) have less
then 32 inputs/outputs. Routing signals to these cards on these higher number signal paths
will have no effect, but because the routing is stored in the console, we support routing to all
signal path numbers no matter which card is installed.
If a card is installed that does not support all 32 signal paths, the unused signal path numbers
are shown in grey indicating that they are still routable but that they are unused. Routing
to/from these greyed out signal paths will therefore have no effect although you can still
make the routing connections. Similarly, if the console does not have a card in slot A and/or
B, the signal paths for the entire card slot will appear in grey again indicating that they are
still routable although no audio will pass. Finally, some cards (LP48) have multiple operating
modes and each mode may have a different number of supported signal paths. Therefore as
the mode is changed, the number of available versus greyed-out source and destination signal
path numbers will change.
The above method allows for cards to be changed while keeping routings intact. Existing
routings will just use the corresponding input/output from the newly added card. This gives
consistent and reliable operation that you can easily understand and change when a new card
is installed and you hear audio you are not expecting.
This operation is described for each card type and mode combination in the table below; note
that each card slot is handled independently:
